Abby shifted uncomfortably, letting the words of the speeches wash over her. She flexed her fingers, missing Connor’s hand next to hers; the casual touch, the reassuring squeeze, the constant presence. That presence was gone, now.

There was so much she had never told him, but it all boiled down to one thing:

She was sweet, they got on well together, she was clearly mad about him, and she was into all the same things he was. They spent many a night discussing the finer details of Star Trek versus Babylon 5 until the small hours of the morning. They made each other happy.

Connor tried to ignore his doubts because everyone agreed that they were perfect for each other.

But as he hugged Abby on the day that he got married to another woman, Connor couldn’t prevent the unwanted thought:

The really sad thing is that in spite of the glee I've got from Series 3, I can actually see it ending up like this. Poor Connor, so convinced he's not worth Abby, and poor Abby, so afraid of actually needing someone (and I wonder why and if we'll ever find out).

Abby *knows* how Connor feels about her. He's told her he loves her, he wears his emotions so openly she can't *not* know. But I think even Connor would eventually give up waiting for her if she never shows him anything in return, which she seems surprisingly unwilling to do, despite what she said to Jenny in 3.2. As you say, it would be interesting to find out why.

I know! It's mad how in the heat of an action situation they can communicate so much to each other just with a look, and yet when it comes to actually dealing with their relationship they are completely unable to talk sensibly, or even at all!
